Description

Technical Field

[0001] This utility model belongs to the field of plant greenhouse cultivation technology, and in particular relates to a temperature control system for flower greenhouses. Background Technology

[0002] As society develops and people's living standards improve, the demand for flowers is also increasing. Generally, flower cultivation sites have greenhouses. Greenhouses are used for insulation, moisture retention, and isolation, which can ensure that the flowers inside can be better cultivated and grown.

[0003] Winters in the north are cold and dry, so it is necessary to heat and humidify the flower greenhouses. The conventional way to heat the greenhouses is to blow hot air directly into them. However, this method is too drying. Therefore, large-scale misting spraying is usually used in conjunction with the greenhouses to humidify them and ensure that the flowers are in a good growing environment.

[0004] While this heating method is relatively direct, it results in uneven heating inside the greenhouse. The temperature is higher near the hot air outlet and lower further away, making it impossible to heat the flowers evenly placed inside the greenhouse. For non-flowering flowers, the water droplets from the mist spray fall onto the leaves, drying into white spots that are difficult to clean and affect normal growth and appearance. When the water droplets fall onto flowering flowers, they reduce the effectiveness of the blooms and shorten the flowering period, directly impacting growers' income. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1-6 As shown, this embodiment provides a temperature control system for a flower greenhouse, including a fence 1, a light-transmitting roof 2 installed on the top of the fence 1, a collection trough 3 detachably connected to one end of the light-transmitting roof 2, a water storage tank 5 connected to the collection trough 3 via a guide pipe 4, a distribution pipe 7 connected to the outlet of the water storage tank 5, the bottom of the fence 1 being adapted to the ground 12, a plurality of temperature and humidity pools being provided on the ground 12, a first heat dissipation component 18 being installed in the temperature and humidity pool, the plurality of first heat dissipation components 18 being respectively connected to a main supply pipe 15 and a main return pipe 16, a plurality of flower rack trays 9 being detachably connected to the top of the ground 12, the flower rack trays 9 being located inside the fence 1, and a plurality of active insulation layers 8 being provided on the top of the fence 1.

[0029] The enclosure 1 is generally made of transparent material, preferably tempered glass. Enclosure 1 is assembled from several tempered glass panels using prefabricated supports, forming a rectangular prism. Its east-west length is longer than its north-south length, and its north side is higher than its south side. The translucent roof 2, also preferably made of tempered glass, is W-shaped. The translucent roof 2 is sealed to the enclosure 1 via prefabricated supports. The south end of the translucent roof 2 is lower than the north end of the enclosure 1. When water is present on the translucent roof 2, it flows through the roof into a collection trough 3, which is fixed to the prefabricated supports. On the support frame, water flows into the water storage tank 5 through the collection trough 3 and the guide pipe 4. The water storage tank 5 is equipped with an overflow pipe 6 to limit the water level and prevent accidents caused by the water storage tank 5 being full. A filter is installed at the connection between the water storage tank 5 and the distribution pipe 7. When water needs to be added to the warm and humidified pool, water can be drawn into the warm and humidified pool through the filter and the distribution pipe 7 via the water storage tank 5. The bottom part of the enclosure 1 is embedded in the ground 12, which serves to insulate against heat and wind. There are several warm and humidified pools on the ground 12 inside the enclosure 1, which can provide sufficient humidity for the flowers. The built-in first heat dissipation component 18 is used to provide auxiliary heat for the flower greenhouse. When the first heat dissipation component 18 dissipates heat, it heats the water in the temperature and humidity pool, further promoting water evaporation and providing sufficient humidity for the flower greenhouse to ensure the normal growth of the flowers. This avoids the impact of directly spraying water mist on the flowers themselves. The flower rack tray 9 can provide support for the flowers off the ground, making it easier for workers to maintain the flowers. The flower rack tray 9 can also further provide temperature for the flower greenhouse. The flower rack tray 9 is close to the flowers and can provide heat to the flowers relatively directly. The heating of the flower rack tray 9 is generally only turned on when the flower greenhouse urgently needs to be heated. Several double-layer active insulation layers 8 are set on the top of the enclosure 1, which can realize modular temperature control and sunlight control, thereby achieving more precise temperature and humidity control and light time control. The active insulation layer 8 is mainly composed of heat insulation cotton. The top surface of the upper active insulation layer 8 is a silver reflective layer, which can reflect light to assist in temperature control. The top surface of the lower active insulation layer 8 is a transparent insulation layer, which can reduce heat consumption.

[0030] Furthermore, the greenhouse temperature control system also includes a central controller. Several temperature and humidity sensors are evenly installed vertically and horizontally inside the enclosure 1. These sensors are electrically connected to the central controller. Several active insulation layers 8 are detachably connected to the enclosure 1 via structural supports. Each active insulation layer 8 is rotatably connected to the output end of a drive motor, which is electrically connected to the central controller. A distribution pipe 7 is connected to a temperature and humidity tank via an electronic switch valve, which is electrically connected to the central controller. The flower rack 9 includes a frame 11, which is connected to the main supply pipe 15 and the main return pipe 16 via pipes through a first metering switch valve. This first metering switch valve is electrically connected to the central controller. A second metering switch valve is installed between the first heat sink 18 and the main supply pipe 15 and the main return pipe 16, and this second metering switch valve is electrically connected to the central controller. Several electrically driven fans are also installed on the enclosure 1, and these fans are electrically connected to the central controller.

[0031] The central controller can monitor the temperature of various areas inside the flower greenhouse. During the winter heating season, when the temperature of a certain area is too low or too high, the central controller, upon receiving the temperature data, will control the corresponding area's active insulation layer 8 drive motor, first metering switch valve, second metering switch valve, or electric drive fan with electrical signals to bring the temperature of that area closer to the optimal temperature range. When the water level in the temperature and humidity pool is too low, the central controller opens the control electronic switch valve to allow water from the storage tank 5 to flow into the temperature and humidity pool through the filter device and distribution pipe 7, thereby adjusting the humidity inside the flower greenhouse. Temperature and humidity sensors are used to detect the temperature and humidity inside the flower greenhouse, providing data support for the central controller. The upper active insulation layer 8 is used to control the light exposure time inside the flower greenhouse and achieve a heat preservation effect, while the lower active insulation layer 8 provides further heat preservation. Electronic switch valves are used to regulate the water level in the temperature and humidity pool. The frame 11 is used to heat the flower greenhouse. The first heat dissipation component 18 is used to heat and humidify the flower greenhouse.

[0032] Furthermore, the temperature and humidity pool includes an outer ring temperature and humidity pool 13 and an inner ring temperature and humidity pool 14. The outer ring temperature and humidity pool 13 is close to the enclosure 1, and the inner ring temperature and humidity pool 14 is located in the middle of the enclosure 1.

[0033] Both the outer ring temperature and humidity tank 13 and the inner ring temperature and humidity tank 14 can be controlled independently. When the temperature inside the greenhouse is too high, the inner ring temperature and humidity tank 14 is closed to maintain the temperature. When it is cold outside the greenhouse, the temperature near the enclosure 1 will be low. In this case, opening the outer ring temperature and humidity tank 13 can solve the problem. This maintains the temperature inside the greenhouse while reducing energy consumption.

[0034] Furthermore, both the outer ring temperature and humidity pool 13 and the inner ring temperature and humidity pool 14 include an outer pool 27 and an inner pool 26.

[0035] Compared to the inner pool 26, the outer pool 27 is closest to the enclosure 1. It can be turned on for heating and humidification according to specific needs. The minimum modular heating and humidification allows for more flexible temperature and humidity control, which can further reduce energy consumption.

[0036] Furthermore, a first heat sink 18 is installed inside the outer pool 27. One end of the first heat sink 18 in the outer pool 27 is connected to the main supply pipe 15 through the first inlet branch pipe 17, and the other end of the first heat sink 18 is connected to the main return pipe 16 through the first return branch pipe 19.

[0037] The first inlet branch pipe 17 and the first return branch pipe 19 are located at the bottom of the passageway between two adjacent flower rack trays 9 and below the ground 12. This arrangement can provide heat to the ground 12 and improve the heating effect.

[0038] Furthermore, a first heat sink 18 is installed inside the inner pool 26. One end of the first heat sink 18 in the inner pool 26 is connected to the main supply pipe 15 through the second inlet branch pipe 20, and the other end of the first heat sink 18 is connected to the main return pipe 16 through the second return branch pipe 21.

[0039] The inner pool 26 is closest to the main supply pipe 15. The second inlet branch pipe 20 and the second return branch pipe 21 between the inner pool 26 and the main supply pipe 15 are relatively short. This arrangement can provide higher heat than the outer pool 27, which is conducive to the rapid heating of the flower greenhouse.

[0040] Furthermore, the inner pool 26 is connected to the adjacent outer pool 27 through a short connecting pipe 22, and the two inner pools 26 that are symmetrically adjacent based on the main supply pipe 15 are connected through a long connecting pipe 23.

[0041] The inner pool 26 and outer pool 27 within the same outer ring temperature and humidity pool 13 or inner ring temperature and humidity pool 14 are connected by a short connecting pipe 22. The inner pool 26 of two adjacent different outer ring temperature and humidity pools 13 or inner ring temperature and humidity pools 14 are connected by a long connecting pipe 23. This ensures that the water level in the temperature and humidity pools on the same line is the same. When the distribution pipe 7 adds water to the temperature and humidity pool, only one outer ring temperature and humidity pool 13 needs to be added.

[0042] Furthermore, the outer pool 27 and the inner pool 26 are also filled with ceramsite and / or sand.

[0043] If the water level is lower than that of expanded clay and / or sand, expanded clay is preferred for filling, followed by a mixture of expanded clay and sand, and lastly, sand is preferred. Filling with expanded clay and / or sand can increase the diffusion of water and also prevent small objects from falling into the water and affecting performance.

[0044] Furthermore, the main supply pipe 15 and the main return pipe 16 are placed vertically, and the main supply pipe 15 and the main return pipe 16 are located in the middle of the ground 12.

[0045] The flower rack tray 9 is rectangular, with its north-south length longer than its east-west length. The flower rack tray 9 is divided into two rows from north to south, with the main aisle in the middle. The main power supply pipe 15 is located in the aisle and below the ground 12. The main return pipe 16 is located below the main power supply pipe 15. This allows the main power supply pipe 15 to provide a certain amount of heat to the main aisle. The main return pipe 16 is at the bottom of the main power supply pipe 15, which can reduce the heat loss at the bottom of the main power supply pipe 15.

[0046] Furthermore, the flower rack tray 9 also includes a tray 10, in which flowers are placed. The frame 11 includes legs 24 and a second heat dissipation component 25. The top of the legs 24 is detachably connected to the tray 10, the bottom of the legs 24 is detachably connected to the ground 12, and the middle of the legs 24 is detachably connected to the second heat dissipation component 25. The second heat dissipation component 25 is connected to the main supply pipe 15 and the main return pipe 16 through pipes.

[0047] When the greenhouse needs to be heated quickly or the air humidity needs to be reduced, the central controller turns on the first metering switch valve to start the second heat sink 25 to start heating. Since the second heat sink 25 is located at the bottom of the tray 10 supporting the flowers, it can provide heat to the flowers or reduce the air humidity in time to achieve the temperature suitable for the flowers. The air humidity is mainly regulated by the electric drive fan, and the temperature can also be regulated by the electric drive fan.
